Molly spread the crayon map across the kitchen table, pinning it with Bill’s expired library card. “The party starts at three. We enter as entertainers, locate the presents, and remove every one before the cake.” “What kind of entertainers? Because the last time you said clown, I explained myself to a horse.” Bill inspected the map: the garden in green, the house in purple, and a menacing stick figure labeled MUM. “Magicians. I have a cape, you have a hat, and neither of us has to put a hand inside anything alive.” “I like it. My hat has a false bottom, although the true bottom fell out during the incident with the soup.” Molly circled a rectangle beside the bouncy castle, where a stack of boxes leaned against a table. “The gifts will be here. We distract the guests, sweep everything into the laundry sack, and walk out smiling.” “What trick? I can make a coin disappear, but only if everyone agrees not to watch me put it in my pocket.” Molly opened a suitcase and produced two rubber chickens, a velvet cloth, and a packet of birthday candles. “We announce the amazing vanishing chicken. You wave the cloth, I squeak the other chicken behind the hedge, and everybody looks away.” “That works if nobody notices the chicken still under the cloth. Children are surprisingly sharp.” Outside, a siren wailed. Bill froze until Molly pointed out that it was their kettle. “Then you hide both chickens. We’ll call it advanced magic. Besides, the invitation says the birthday boy specifically requested a surprise.” “A boy named Oliver, aged seven. Do you think his big surprise might be receiving presents rather than watching strangers steal them?” Molly looked at the invitation again. Her confident expression slipped sideways, like a badly secured toupee in a stiff wind. “We are not stealing his presents forever. We are relocating them temporarily, then returning them with a tremendous flourish. That’s entertainment, apparently.” “That sounds suspiciously like doing an honest job. Will there at least be a getaway vehicle, or must we take the bus?” She pointed to a drawing of a bicycle with a trailer. Bill squinted at its tiny square wheels. “We take my bicycle. The sack goes in the trailer, we circle the block, and I return dressed as the Great Molini.” “And what do I do while you’re cycling? I refuse to wrestle a bouncy castle again, whatever the children offer to pay.” Molly handed him the velvet cloth. He held it up, and a rubber chicken fell out. “You guard the cake and keep everyone cheering. When I reappear, you shout, ‘Behold!’ as loudly as your professional dignity permits.” “I can do that. But if we’re returning everything, how exactly do we make any money from this criminal enterprise?” Molly tapped the invitation, where a fee had been circled twice. “Oliver’s mother pays us fifty pounds, plus cake. The real crime, Bill, is how long it took us to discover legitimate employment.”
